Keyboard/boot & sleep mode issue

1) Today, Vista has not recognized my ps2 keyboard. It works fine during boot-up, and works fine when in setup. But once Vista 'welcome' screen appears, the keyboard is useless.
I can go into setup and use keyboard just fine, but it's dead once boot is done.

This problem arose this morning.....normal bootup as usual.

I'm typing this via USB keyboard.

2) Sometimes this pc just will not come out of sleep mode unless I do a hard boot.
Right now, the power save settings are:

Turn off display: Never
Put computer to sleep: Never

I have a dual monitor system:

I left the room for 30 minutes and came back to find both monitor screens black.
(The screen saver should have been running.....it was not.)

I moved the mouse and the 2nd monitor came to life while the main monitor went to sleep.......followed by the 2nd monitor......I could still hear the fan running.....I had to hard boot to shut down.

Often, when in sleep mode, the keyboard is completely unresponsive.


THANKS!!!!!!!
